+[AutoConnectConfig::tickerPort](apiconfig.md#tickerport) specifies a port that outputs the flicker signal. If you are using an LED-equipped ESP module board, you can assign a LED pin to the tick-port for the WiFi connection monitoring without the external LED. The default pin is arduino valiant's **LED\_BUILTIN**. You can refer to the Arduino IDE's variant information to find out which pin actually on the module assign to **LED\_BUILTIN**.[^3]

+[^3]: It's defined in the `pins_arduino.h` file, located in the sub-folder named **variants** wherein Arduino IDE installed folder.
[AutoConnectConfig::tickerOn](apiconfig.md#tickeron) specifies the active logic level of the flicker signal. This value indicates the active signal level when driving the ticker. For example, if the LED connected to tickPort lights by LOW, the tickerOn is **LOW**. The logic level of LED_BUILTIN for popular modules are as follows:
-module | Logic level
